This invention relates to an automobile radiator cap securing device and the primary object ot myi'nventio'n is to 'furnish a radi ator iilling Connection with a cap held in place byfbayonet slot and pin connections, with a securing ring adapted to bel adjusted to hold the cap so that it cannot be surreptitiously removed. Y

Another object oi this ini'ention is to provide a cap and cap connect-ion that may be substituted for an ordinary radiator cap, and the principle of ,my improved cap connection is applicable to various kinds of closures, for instance the lids of milk cans and other receptacles.` j i i A still `further object'oi' my invention is to accomplish the above results by a simple, dura-ble and inexpensive construction that will be hereinafter specifically described and then claimed,

Reference will now be had to the drawing, vwherein Figure 1 is a front elevation of a portion ot the radiator' provided with a cap connection and cap in accordance with this invention;

Fig. 2 is a vertical sectional view of the radiator filling connection provided with a cap in accordance with my invention;

Fig. 3 is a horizontal sectional View taken on the line III-III of Fig. 2;

Fig. 4 is a side lelevation ot' a cap partly broken away and partly in section showing the cap in a secured position;

Fig. 5 is a view similar to Fig. 2 showing the cap partly engaged with the filling connection; l

Fig. 6 is a side elevation ot the same partly broken away;

Fig. 7 is a side elevation of a modified form of connection;

Fig. 8 shows views of a modified form of securing ring, and

Fig.4 9 is a side elevation ot' another 'form ot radiator connection for the securing ring shown in Fig. 8.

In the drawing, the reference numeral 1 denotes a portion of a radiator having a filling connection 2 which isexteriorly screwthreaded, as at 3, such being the usual and well known filling connection adapted to be closed by an ordinary screw cap.

When radiators are made the connection 2 may take the form of a connection 4,y shown in Figs. 2 and 5, said connection having its upper end reducedas atl` 5, and

eXteriorly sc-rewthreaded as at 6. Thereduced end 5 of th-e connection 4 is provided with` a plurali-ty of bayonet or angle slots, each having a ver-tical portion 7 a horizontal portion 8 vand a return or socket portion `9, so that YVeach slot is substantially -L Vor 'J shaped in elevation; i

, 10 denotes a cap having a neck 11 adapted to `lit in the reduced end 5 ot the connection 4 and said neck is provided with outwardly extending 'studs 12 corresponding in A number to the slots ot'` the connection 4. Vhen placing the cap 10 in engagement with `the connection 4 the. studs 12 enter :the vertical portions 7 or the slots'and when thecap has been pushed downwardly as tar as possible, it is turned in a counter vclockwise,direction to carry the studs 12 through the horizontal portions 8 of the slots and place the studs in vertical alinement with the socket or return portions 9 of said slots. Y

Adjustably engaging the screw threads 6 of the connection 4 is a securing ring 13 and after the neck 11 of the cap 10 has been positioned, as mentioned above, the securing ring 13 can be adjusted to raise the cap 10 relative to the connection, thereby carrying the studsy 12 into the sockets or return portions 9 of the slots, as shown in Fig. 4. The cap will be bound in place and cannot be partially rotated and removed, untilthe ring 13 is adjusted to recede from the cap and permit of the cap being lowered, partially rotated and then removed.

In order that my improvement' may be used with the connection 2, the connection 4 may be made as a short sleeve, and interiorly screwthreaded to screw on to the connection i 2, thus adapting my improvement to the usual construction, but when radiators are manufactured the connection 4 can be made an integral part thereof.

Instead of providing the radiator connection with one way slots, I may provide it with'substant-ially inverted T-shaped slots 14 which will permit of the cap being turned in either direction and held in their position by the securing ring` 13.

I may also provide a radiator connection with straight vertical slots 15 to receive the studs 12, and in the threaded wall of a securing ring 16 I may provide angular grooves 17 to receive the studs. The studs in suchl groovewill necessarily limit radiation ofthe securing ring 16, but permit of the screw threads of said securingring to cause the ring to bind the studs 1n engagement with said ring, so that the radiator cap is` lirmly held in place. V y

From the foregoing it will be observed that the securing ring will anchor the radiator cap in place and prevent accidental displacement thereoty when the studs or pins properly engage in the angle slots. The cap cannot be rotated when properly secured and in some instances the ring 13 may be tightened by using a suit-able tool so that it cannot be rotated by hand, thus `preventing the radiator cap or any instrument or orna mentation carried thereby fromv being stolen. For instance, my caps are provided with motormeters and the instance has been known where such caps are removed and the ordinary cap substituted therefor'. This nefarious practice is growing and my invention aims to prevent surreptitious removal'of a cap by securing it in such a manner that it cannot be conveniently removed.

lVhile in the drawings there are illustrated the preferred embodiment of my invention, it is to be understood that the' structural elements are susceptible to such variations and ing studs carried by the neck of said cap and extending into the slots of said connection Y and adapted to engage in the return portions of said slots, and a ring screwed on said'fillingconnection adapted to be shifted to cover said slots and engage under said cap to forcef said cap upwardly from said connection and hold said studs in the return portions of the connection slots. i

2. A radiator filling connection provided with slots, a cap havingr a neck to it in the filling connection and cover said slots, studs carried by the neck of Said cap and extending into the slots of said connectionfand a ring on said filling connection adapted to be shifted to cover said slots and secure said studs against movement relative to said filling connection.

In testimony whereof I afiix my Signature.V
